Al Gonzales admits to more NSA spying programs?

I don't know quite what to make of this,

Attorney General Alberto R. Gonzales appeared to suggest yesterday that the Bush administration's warrantless domestic surveillance operations may extend beyond the outlines that the president acknowledged in mid-December.

In a letter yesterday to senators in which he asked to clarify his Feb. 6 testimony to the Senate Judiciary Committee, Gonzales also seemed to imply that the administration's original legal justification for the program was not as clear-cut as he indicated three weeks ago.

At that appearance, Gonzales confined his comments to the National Security Agency's warrantless wiretapping program, saying that President Bush had authorized it "and that is all that he has authorized."

But in yesterday's letter, Gonzales, citing that quote, wrote: "I did not and could not address . . . any other classified intelligence activities." Using the administration's term for the recently disclosed operation, he continued, "I was confining my remarks to the Terrorist Surveillance Program as described by the President, the legality of which was the subject" of the Feb. 6 hearing.
